Hyginox SH Introduction 1.1

B. Technical principles. Quantity Symbol Unit Dinamic viscosity μ mpa.s (=cp=centipoise) V=μ/ρ with ρ=specific weight [Kg/dm 3 ] Kinematic viscosity and V = kinematic viscosity [mm 2 /s] = cst = Centistoke Only the dynamic viscosity is used in this manual. p [bar] Pressure Δp [bar] - differential pressure Pm [bar] - maximum pressure at discharge mouth (design pressure) Unless otherwise indicated, in this manual pressure is understood to be relative pressure. NPSH [m] In this manual, NPSH = NPSHr (NPSH required for the pump). NPSHr = the net pressure above the liquid vapour pressure at pumping temperature and at the pump inlet connection required to avoid performance impairment due to cavitation Net positive suction at rated capacity. NPSHr is measured at the suction flange at the point where the capacity head (NPSH) drop = 4% of the rated capacity, and is corrected to the datum elevation. NPSHa = the total suction pressure available from the system at the pump suction connection, minus the vapour pressure if the liquid at pumping temperature. NPSH available is calculated for the installation. It is the responsibility of the user to determine this value. NPSHa NPSHr + 0,5 Symbols. It is absolutely necessary to place symbols on the pump, e.g., arrows which indicate the direction of rotation or other symbols indicating connections to fluids. All of these symbols should be clearly visible and legible. Training and experience. The personnel who are responsible for the operation, maintenance, inspection and assembly of the equipment should have the proper experience and training. The scope of their responsibilities and the supervision of the operators should be specifically defined by the plant foreman. If the operators did not have the required knowledge, they should be trained, which could be done by the manufacturer of the machine or by the supplier on behalf of the shop foreman. Furthermore, the shop foreman should make sure that the contents of the instruction manual are fully understood by the operators. In accordance with the instructions. Any failure to comply with the instructions could lead to a hazard for the operators, the atmospheric conditions of the room, and the machine, and it could lead to a loss to any right to make a claim for damages. Such non-compliance could bring with it the following risks: Important operating failures of the machine / plant. Failure to comply with specific maintenance and repair procedures. Potential electrical, mechanical and chemical hazards. Atmospheric conditions in the room could be hazardous due to the release of chemical substances. In accordance with the regulations governing safety at work. The instructions contained in this manual should be followed for operating the pump, along with national regulations and any other service and safety instructions made available by the shop foreman, so as to avoid accidents. Safety instructions for handling. If the machine's components, whether in a cold or warm state, constitute some hazard, then accidental contact with the same should be avoided.

3. General Information DESCRIPTION. The sanitary centrifugal pumps in the HYGINOX SH series are manufactured using AISI 316 stainless steel die-pressed steel plate with an electro-polished finish. The HYGINOX SH centrifugal pump has a compact construction, monoblock, axial intake, radial discharge, and sanitary-type connections. The impeller is of open design and made of one single piece. The mechanical seal is according to DIN 24960 L 1 K. The friction surfaces are silicon carbide, graphite and the EPDM o-rings in the standard version. The motor conforms to the IEC standard with a stainless steel facing. IP-55 protection. Class-F insulation. Three-phased power supply with 220-240 / 380-420 / 660 V at 50Hz, depending on the power source. The motors can be ordered for working in explosion hazardous environments. Depending on environmental conditions, the motors can be explosion-proof (EExd) or of enchanced safety (EExe). The HYGINOX SH series has been specially developed to respond to all hygienic requirements in the food industry. As regards hygiene, reliability and sturdiness, the complete range satisfies all requirements set by the aforesaid industry. Thanks to its design, there is optimal interchangeability of parts between the different pumps. This equipment is suitable for his use in food process. PRINCIPLE OF OPERATION. The rotor or impeller, situated in the housing, rotates solidly fixed to the pump shaft and consists of a given number of blades, depending on the pump model. The impeller blades transmit energy to the fluid in the form of kinetic and pressure energy. The pump is not reversible by simple inversion of the direction of rotation. The direction of rotation is clockwise when the pump is seen from the rear part of the motor. NOISE. Particularly when the type of use to which the pump is put determines the level of noise to which the operator is exposed as a result of its handling and installation --if it is similar or greater than 85 dba-- measures as prescribed in regulation no. 277 dated 15/8/91 should be adopted in order to protect users from the risks which this entails. When the noise level in the operating area exceeds 85 db(a), use special protection. APPLICATION. As a general rule, the standard version of the HYGINOX SH pumps are used to transfer liquids for the food industry. Subject to special design, they can be used in concentrators, closed tanks, evaporators, distillation towers, etc. The hydraulic performance at various impeller diameters and different speeds is given for each of the pump types. The curves also show the power required and the NPSH required. HYGIENE. Special attention has been given to hygiene and cleaning requirements in the construction of the pump. The number of grooves and dead spaces have been limited to an absolute minimum. The pump can be cleaned easily and thoroughly in either of the two following ways: without disassembling it, for ex.: by means of steam or water, referred to as CIP (Cleaning in Place). by easy disassembly of the pump housing, the impeller and the mechanical seal. Refer to chapter 10 (Cleaning and disinfection) on how to properly clean the pump and the methods and products to be used. Hyginox SH centrifugal pumps by INOXPA have been approved by the American 3A Standard Authorities. MATERIALS USED IN CONSTRUCTION. All pump parts which are in contact with the product are stainless steel, or are made of tasteless and odorless materials. This makes the pump resistant to corrosion and avoids contamination of the liquid being pumped. It is necessary to check and verify that the materials in contact with the product are made for pumping a product which is specifically for human consumption.. ED. 12.02/08 3.

4. Installation GENERAL CONSIDERATIONS. This manual provides basic instructions which should be taken into account when proceeding to install the pump. It is of utmost importance that the shop foreman read this manual before assembly. The instructions include pertinent information which will enable you to install your pump correctly. The manual also contains important instructions for preventing possible accidents and serious damage which could occur prior to start up and during the installation : It is imperative to put warning markers on the pump, e.g., arrows which indicate the direction of rotation or symbols indicating fluid connections. All these warnings should be clearly visible and legible. Any failure to comply with the instructions could result in a risk for the operators, the surroundings and the machine, and could result in the loss of any right to make a claim for damages. INSTRUCTIONS UPON DELIVERY, FOR TRANSPORT AND STORAGE. When the machine arrives, read the instructions on page 1 of the chapter titled "Introduction". Hyginox SH pumps are often too heavy to be stored manually. Use an adequate means of transport. Use the points which are indicated in the drawing for lifting the pump. Only authorized personnel should transport the pump. Do not work or walk under heavy loads. Figure 4.1: Lifting the pump. LOCATION. Piping. Place the pump as close as possible to the suction tank (refer to the chapter, "Pump Installation"), and if possible below the level of the liquid or even lower in relation to the deposit so that the static manometric suction head is at its maximum. Place the suction and discharge piping in straight runs with a minimum of elbows and fittings in order to reduce to the extent possible any loss of head caused by friction. This improves the suction conditions, thereby affording maximum performance of the pump. Accessibility. Place the pump so that access can be had to the pump and to the drive units so as to make inspections and revisions. Leave sufficient space around the pump for proper inspection, separation of the pump from other units and for maintenance operations. In order to disassemble the pump you should leave sufficient space in front of and behind it. (Chapter 9 deals with the dimensions). Place the pump with sufficient space for the lifting equipment if the components or the total weight of the unit exceed 22 kg. Place the pump near the drain on the floor. It is very important to be able to gain access to the pump connecting device (including when it is operating). Outdoor installation. The HYGINOX SH pump can only be installed out of doors if there is a roof covering. Consult with prior to installation. ED. 12.02/08 4. Hyginox SH Installation 4.1

Place the pump so that the motor is properly ventilated. Prepare the motor to be started according to the instructions provided by the manufacturer. When inflammable or explosive liquids are pumped, an adequate connection needs to be used. Connect the components of the unit with grounding jumpers in order to reduce the danger from static electricity. Use explosion-proof motors in accordance with national and local standards and regulations. Excessive temperatures. Depending on the fluid to be pumped, high temperatures can be reached inside and around the pump. Over 70 ºC the operator should take protective measures and place warning notices advising of the danger which exists if the pump is touched. The type of protection selected should not isolate the pump entirely. It should allow for optimum cooling of the motor. STABILITY. Foundation. Prepare the foundation so that the pump is level and well supported. Its emplacement should be rigid, horizontal, flat and resistant to vibrations, so as to avoid any warping (if the pump's alignment is maintained its operation is ensured during start-up). 4. Hyginox SH Installation 4.2 ED. 12.02/08

HANDLING. If the pump is supplied without a motor, the purchaser/user is responsible for the pump's start-up and assembly. ELECTRIC MOTORS. Regulations. Prior to connecting an electric motor to the power supply, check local regulations on electrical safety and also refer to the EN 60204-1 standard. Let qualified personnel perform the connection of electrical motors. Take the necessary steps to prevent faults in the connections and wiring. Automatic switch. In order to work on the pump without hazards, an automatic switch should be installed as close as possible to the pump. The use of a grounding switch is also recommended. The equipment used for handling the pump should comply with current regulations, as set forth in the EN 60204-1 standard on electrical safety. Protection of the motor against overloads. In order to protect the motor from overloads and short circuits, the use of thermal or magnetic relays is recommended. Adjust these relays to maximum rated current values as indicated on the data plate of the motor. Connection. Consult the supplier's instructions prior to connecting the motor to the power net. For single-phase motors, use motors with an increased starting torque. Ensure a starting torque which is sufficiently high for motors controlled by a frequency changer, and which provide for adequate cooling at low speeds. If necessary, install an independent fan. The electrical equipment, the terminals and the control system components can continue to carry current when disconnected. Any contact with them can endanger the safety of the operators or cause irreparable damage to the material. DIRECTION OF ROTATION. The direction of rotation is clockwise viewing the pump from the rear part of the motor. Electrical diagram. Make sure that the pump rotates in the direction indicated on the plate. If the pump rotates in the wrong direction its hydraulic performance will be lower. Connection U=... 3x220 3x380 motor 220/380 Δ 380 - Δ SUCTION AND DISCHARGE PIPES. Figure 4.2: Electrical Connections ED. 12.02/08 4. Hyginox SH Installation 4.3

Excessive forces and tensions on pump connections, caused by the piping, could result in mechanical damage to the pump. These pipes should be connected in a straight line, without leaving spaces between connections and the faces of parallel connections. Provide for adequate anchoring devices and make sure that they are not tensed too much when the pump is operating. When hot liquids are pumped, pay attention to thermal expansion; if this is the case, use expansion joints. Once the connection has been made, check that the shaft can turn freely. Pipes. Use pipes with a diameter which is equal to or greater than that of the pump's connections. If the liquid to be pumped is viscous, the loss of head from the suction and discharge pipes can increase considerably. Other pipe components such as valves, elbows, filters and foot valves, can also cause a loss of head. For this reason, the diameters and the length of pipes and other components should be selected so that the pump will operate within the minimum pressure limits allowed for the suction (refer to NPSH graph), the maximum working pressure (refer to chapter 3, "Field of Application"), and the rated motor power. Suction pipe. Liquids should be introduced into the pump from a higher level than that of the pump; the pipe should be inclined in its path to the pump and devoid of air pockets. A diameter which is too small or a suction pipe which is too long, a filter too small or clogged, will lead to a greater loss of head and thus the NPSH available (NPSHa) is less than the required NPSH (NPSHr). Cavitation may occur, causing noise and vibrations. The possibility that the pump may also suffer mechanical If a filter is installed in the suction mouth, a constant check for loss of load in the suction pipe should be made. Also check to see whether the suction pressure at the suction mouth of the pump is sufficiently high (see NPSH). Check the tension of the suction pipe after its connection. Self-priming process. In general terms --if the self-priming process is followed-- it is necessary for the pump to contain sufficient liquid to fill the housing, enabling the pump to create a pressure difference. However, if the pump does not operate with a load, a foot valve which has the same or a greater diameter as that of the suction pipe should be installed; or the pump can be installed with a self-priming housing. The use of a foot valve is not recommended for pumping viscous liquids. In order to eliminate air and gases from the suction pipe, the counter-pressure on the discharge pipe should be reduced. When the self-priming process is used, the pump's start-up should be done by opening and emptying the discharge pipe which allows the air and gases to escape at a low counter-pressure. Another possibility involves long pipes or when a check valve is installed in the discharge pipe; it is also possible to install a by-pass with a shut-off valve on the discharge side of the pump. This valve will open in the case of priming and will allow air and gases to escape at a minimum counter-pressure. The by-pass should not lead back to the suction mouth but rather it should lead to the supply tank. Shut-off valves. The pump should be isolated for proper maintenance. This isolation can be obtained by installing shut-off valves in the suction and discharge pipes of the pump. These valves should be able to open completely, both for suction and for discharge, as occurs with the suction and discharge pipes (ball-checks or sluice valves are preferable). When the pump is started up, the shut-off valves should be completely open. The flow rate should never be regulated by closing the shut-off valve in the suction or discharge pipe. The flow rate is to be regulated by increasing or decreasing the pump's speed, trimming the impeller, or using a by-pass which re-directs the flow to the supply tank. Filters. Foreign particles can seriously damage the pump. Avoid the entry of these particles by installing a filter. When selecting a filter, bear in mind the diameter of the screen openings so that loss of head will be minimal. The filter diameter should be three times greater than that of the suction pipe. The filter should be placed in such a way that it does not interfere with maintenance and cleaning operations. Be sure that the density of the liquids is appropriate and that they can be filtered easily. 4. Hyginox SH Installation 4.4 ED. 12.02/08

5. Start-up GENERAL CONSIDERATIONS. The pump can be started up so long as the instructions given in chapter 4 ("Installation") have been followed. CLEANING. Prior to start-up, the persons responsible for the operation must be duly informed of the pump s operation and the safety instructions. This instruction manual should be available to personnel at all times. Prior to start-up, check the pump for any possible failure. If a failure is found, the plant foreman should be notified immediately. Also consult the section "Dimensions" in chapter 9. Prior to start-up, check to see that the pipes and the pump are completely clean and devoid of weld spatterings or other foreign particles. Consult chapter 10 (cleaning and disinfection) on how to properly clean the pump and the methods and liquids which should be used. Completely open the shut-off valves in the suction and discharge pipes. If the liquid does not flow into the pump, fill it with liquid when pumping. The pump should never rotate when empty. If the pump has a heating chamber, open the valve for feeding in the heat source. Wait at least 15 minutes for the pump and the liquid in it to reach the correct working temperature. Rotate the shaft by hand to check the unfreezing of the pump. Open the shut-off valve for the secondary washing circuit; if the pump is equipped with a cooled seal, a pressure greater than the working pressure of the pump is not needed in the cooling chamber. Check to see if the pump can be started up safely. Start the pump. Check to see whether the absolute suction pressure is sufficient, so that vapour cannot be produced inside the pump. Refer to the curve for the minimum pressure required above the vapour pressure (NPSH). Control the discharge pressure. A shut-off valve should not be used in the suction pipe to regulate the flow rate. It must be completely open during operation. ED. 12.02/08 5. Hyginox SH Start-Up 5.1

6. Maintenance GENERAL CONSIDERATIONS. Inadequate, wrong or improper maintenance could result in the faulty operation of the pump, high repair costs, and breakdown in the long run. For this reason the instructions given in this chapter should be followed. During maintenance operations which are performed on the pump, whether due to inspections, preventive maintenance or the movement of the installation, the procedures indicated should always be followed. Failure to comply with these instructions could endanger the operator and/or seriously damage the pump. Maintenance work should only be done by qualified personnel. Wear appropriate clothing which provides adequate protection against high temperatures and hazardous and/or corrosive fluids. Make sure that the personnel read the entire instruction manual and, in particular, indicate to them the chapters which refer to work which needs to be done. INOXPA does not assume responsibility for accidents and damage which might occur as a result of any failure to comply with the instructions indicated herein. PREPARATION. Work area. Provide for a clean work area; some parts are extremely delicate and others support small tolerances. Tools. Use tools which are designed for the purpose for which they are to be used in maintenance and repair work. Use them properly. Disconnection. Before beginning maintenance and inspection work, disconnect the pump. Decompress the pump and the pumping unit. If the fluid to be pumped allows for it, let the pump cool down until it reaches room temperature. Safety. Do not let the motor start if work needs to be done on the pump. This is very important when electric motors are involved which are connected from a certain distance. Follow the procedure outlined below: Place the pump switch in the "Off" position. Disconnect the pump from the power supply. Block the electrical control panel or put a warning notice on it. Remove the fuses and take them with you to the work area. Do not remove the protection pieces located around the lantern until the pump is completely stopped. CONSERVATION. Should the pump be taken out of service for a long period of time: First of all, empty the pump. Apply VG46 mineral oil to the internal parts. The pump should be worked on for a brief period of time once a week or the shaft rotated manually. This ensures the correct circulation of the protective oil. EXTERNAL CLEANING. Attempt to keep the exterior of the pump clean at all times. This helps in inspection work and keeps warning notices visible. Make sure that cleaning products do not get into the motor's ball bearings. Cover all parts which should not enter into contact with the cleaning fluid. Do not spray hot parts of the pump with water as some components could crack due to quick cooling and the fluid inside the pump could spill out. ED. 12.02/08 6. Hyginox SH Maintenance 6.1

ELECTRICAL INSTALLATION. Maintenance work on electrical installations can only be done by qualified personnel and only when the power supply has been cut off. Carefully follow national safety regulations. Also abide by the regulations referred to above if you are working while the power supply is still connected. Check to see whether the electrical materials to be cleaned are well protected (for ex., IP 54 indicates protection against dust and water spray but does not include protection against pressure water jets). Consult EN 60529. Choose an appropriate method of cleaning electrical materials. Replace defective fuses with new ones having the prescribed amperage. On finishing each maintenance operation, check the electrical installation components to see if they are defective and repair them if necessary. MAINTENANCE. Periodically check suction and discharge pressures. Inspect the motor in accordance with the manufacturer's instructions. In general, a mechanical seal does not require maintenance; however, the seal should never be made to work when empty. Should a leak occur, replace the seal. 6. Hyginox SH Maintenance 6.2 ED. 12.02/08

Purge or fill. 4 Cavitation. Increase suction pressure (also see 2) 5 The pump sucks in air. Check the suction pipe and all its connections. 6 Suction pipe obstructed. Check suction pipe and the filters, if any. 7 Discharge pressure too high. If necessary, reduce head losses, for ex., by increasing the pipe diameter. 8 Flow rate too high. Reduce the flow rate: - Reduce the flow rate using a diaphragm. - Partially close the discharge valve. - Trim the impeller. - Decrease the speed. 9 Viscosity of liquid too high. Reduce the viscosity, for ex., by heating the liquid. 10 Temperature of the liquid too high. Reduce the temperature by cooling the liquid. 11 Damaged or worn mechanical seal. Replace the seal 12 O-rings not the right ones for the liquid. Insert the proper O-rings; check with the supplier. 13 The impeller scrapes. - Decrease the temperature. - Decrease the suction pressure. - Adjust the clearance between the impeller and the housing. 14 Tension in the pipelines. Connect the pipelines to the pump free of tension. 15 Foreign objects in the liquid. Place a filter in the suction. 16 Mechanical seal spring tension too low. Adjust as indicated in the manual. 17 Pump speed too low. Increase the speed. 18 Suction shut-off valve closed. Check and open. 19 Discharge pressure too low. Increase the pressure: - Increase the diameter or the impeller. - Increase the speed of the pump. If the problems persist stop using the pump immediately. Contact the pump manufacturer or his representative. ED. 12.02/08 7. Hyginox SH Operating Problems 7.1

8. Disassembly and Assembly GENERAL CONSIDERATIONS. The assembly and disassembly of the pumps should only be done by qualified personnel. Make sure that the personnel read carefully this instruction manual and, in particular, those instructions which refer to the work they will perform. Incorrect assembly or disassembly may cause damage in the pump's operation and lead to high repair costs and a long period of down-time. INOXPA is not responsible for accidents or damages caused by a failure to comply with the instructions in this manual. Preparations. Provide for a clean working environment as some parts, including the mechanical seal, are very delicate and others have little tolerance. Check that the parts which are used do not suffer damage during transport. When doing this, you need to inspect the adjustment edge, the butted faces, clogging, burrs, etc. After each disassembly, carefully clean the parts and check for any damage. Replace all damaged parts. Tools. Use the proper tools for assembly and disassembly operations. Use them correctly. Tightening torque. Table 8.1: Tightening torque Material Tightening torque N.m. M5 M6 M8 M10 M12 M14 M16 M18 M20 8.8 6 10 25 49 86 135 210 290 410 A4 5 9 21 42 74 112 160 210 300 Cleaning. Before disassembling the pump, clean it on the outside and on the inside. NEVER clean the pump by hand when it is running. Safety. Prevent the motor from starting if you need to work on the pump. Take steps to ensure that the motor cannot be started if the pump housing is removed, for ex., for cleaning operations. NEVER cause the pump to run without the housing. Disconnection. Before beginning disassembly and assembly work, disconnect the pump. Decompress the pump and the pumping unit. If the fluid in the pump allows for it, let the pump cool off until reaching room temperature. Electrical safety. Prevent the motor from starting if you need to work on the pump. This is very important when working with electric motors that are connected from a certain distance. Follow the procedure outlined below: Place the pump switch in the "Off" position. Disconnect the pump from the power supply. Block the electrical control panel or put a warning notice on it. Remove the fuses and take them with you to the work area. Do not remove the protection pieces located around the lantern until the pump is completely stopped. ED. 12.02/08 8. Hyginox SH Disassembly and Assembly 8.1

DISASSEMBLY AND ASSEMBLY. PUMP HOUSING. Close the suction and discharge valve. ATTENTION! The liquid can spill out when the pump housing is removed. Remove the clamp (15). Check to see that the O-ring (80A) is still in good condition. Make sure that the O-ring is not inverted when inserted. Once the pump housing is assembled the clamp needs to be inserted and the wing nut tightened. DISASSEMBLY OF THE IMPELLER AND THE PUMP COVER. Remove the pump housing as indicated in the foregoing section. Remove the screw (50A) and the protection (47A). Insert open-jaw wrench in the shaft flats (05) to keep it from rotating. Remove the nut (45) and the washer (35). Remove the impeller (02). If necessary, hit it with a dead blow using a plastic mallet in order to drive off the cone. Remove the rotating part of the mechanical seal (08). Remove the pump cover (03). The stationary part of the mechanical seal (08A) remains in place on the pump cover. MECHANICAL SEAL. Disassembly of the single mechanical seal. Disassemble the single mechanical seal as indicated in the section on "Disassembly of the impeller and the pump cover". When the impeller is removed, the rotating part of the mechanical seal (08) remains attached to the shaft of the pump. Check that the sealing surface of the rotating face and the seal are in good condition. When the pump cover is disassembled, the stationary part of the mechanical seal (08A) comes off from the cover. Check to see that the sealing surface and the O-ring are not damaged. Assembly of the single mechanical seal. Fit the pump cover (03) on the lantern (04). The stationary part of the mechanical seal (08A) needs to be inserted first into its location in the cover. Slide the rotating part of the mechanical seal (08) over the shaft. Fit the impeller as indicated in the corresponding section. WARNING! When fitting the new seals, be sure to wet the O-rings with soapy water so that the fixed parts slide easily into their locations and the rotating parts onto the shaft. ASSEMBLY OF THE IMPELLER. Slide the impeller (02) over the shaft up to the rotating part of the mechanical seal (08). Place an open-jaw wrench on the shaft flats (05) to keep it from rotating. Slide the impeller washer (35) into place ant tighten the nut (45). Check that the clearance between the impeller and the cover (03) remains at 0.3-0,5 mm so that the working pressure of the seal would be the correct one; see Figure 8.1. 8. Hyginox SH Disassembly and Assembly 8.2 ED. 12.02/08
